Pathfinder: Adapting Virtual Museums for the Differently Abled
Introduction
Many technologies exist to
help people with disabilities use computers to overcome their handicaps.
With the advent and prevalence of the World Wide Web, new sources of information
are now more available to a traditionally underserved population.
It is important for the designers of virtual museums to keep in mind that
the virtual museum web site may provide the best or only access to the
museum’s collection for a person with disabilities. In order to better
serve computer users with different abilities, web designers should be
informed about the adaptive technologies the differently abled use to access
the Internet, and designers should also consider the aspects of web design
that will make the virtual museum more compatible with these technologies.
This pathfinder encompasses
the dual purposes of educating web designers about assistive technology
and introducing resources to guide designers in adapting virtual museums
for the differently abled. I have written this pathfinder for students
researching virtual museums in the Information Resources in the Humanities
class at the University of Texas Graduate School for Library and Information
Science. I have chosen to include only resources that students can
easily access on the UT campus and on the Internet through no-fee services.
Another criterion for selection is that each resource include a significant
portion about how people with disabilities access the Internet or guidelines
for adapting web sites for the differently abled.
What technologies are available to assist people with disabilities in using computers?
In beginning research on the topic of adapting virtual museums, I first looked at UTNetCat for resources about assistive technology for the disabled. The Library of Congress Subject Heading for this field is “Computers and the Handicapped.” Many of the sources I reviewed were outdated or provided a broad overview of computer adaptations without specifically addressing web access. For the most up-to-date print resources on assistive technology, examine conference proceedings cataloged under the subject heading “Computers and the Handicapped--Congresses.” Indexes and databases such as ERIC, available under “Indexes, Abstracts, and Full Text” on UT Library Online <http://www.lib.utexas.edu/>, provide resources on adaptive technology, but the few articles specifically on web design for the disabled are difficult to access.
How can I design and evaluate an accessible web site?
While many computer add-ons and software programs allow the differently abled to access virtually any information on the Internet, there are steps a designer can take to increase accessibility and compatibility. After learning about the different technologies available for a variety of disabilities, I searched for information about web design for accessibility. Design books are cataloged under the subject heading “Web sites--Design,” but few of the books I examined contained a significant amount of information about universal design. For accessibility guidelines, the most recent and useful sources can be found on the Internet by combining search terms such as “universal design,” “web design,” “accessibility,” and “disabled.” The most authoritative web pages about accessible web site design include extensive links to organizations, guidelines, and evaluation tools for web designers.
An online version of “Pathfinder:

ACM Conferences “provide a forum where researchers and developers from academia and industry can meet to exchange ideas and report on leading edge developments relating to computer based systems to help people with disabilities” (Jaffe 1996, ii). The focus of the second conference is on universal design in education. The proceedings include abstracts and articles from the presentations on topics such as “User Interface” and “World Wide Web Issues.” These proceedings provide a valuable collection of scholarly writings on the latest developments in adapting hardware, software, and the Internet for use by persons with disabilities. The proceedings include a table of contents (articles are grouped according to conference session topic), author index, and keyword index.

These proceedings include brief technical papers on a variety of technological developments arranged by date and time of the presentation. Readers can more easily access information about specific technologies or disabilities through the keyword index. Virtual museum designers may find articles such as “Making VRML Accessible for People with Disabilities” and “Haptic Virtual Reality for Blind Computer Users” of interest.

This collection of articles about developments in adaptive technology that enable people with different abilities to more easily use computers are grouped by the type of disability: “hearing, speech, and language”; “learning disabilities and mental retardation”; “neuromuscular and neurological”; “vision”; and “non-specified.” The proceedings are useful to designers of virtual museums because they include information on new technologies, some inexpensive, that make graphic interfaces more accessible to the disabled. The reader can access information through the arrangement by disability or the author index.
